At-the-Market Sales Agreement

On December 21, 2021, we entered into an At-the-Market Offering Sales Agreement, or ATM, with Virtu Americas, LLC, as sales agent. The ATM was terminated on February 29, 2024, and no further sales of our common stock will be made pursuant to the ATM.

Since entry into the ATM, through the date of termination of the ATM, we offered and sold an aggregate of 200,000 shares of our common stock. These aggregate sales resulted in gross proceeds to us of approximately $1.5 million. During the three and six months ended June 30, 2024, we did not sell any shares of our common stock pursuant to the ATM.

May 2023 Registered Direct Offering

In May 2023, we entered into a securities purchase agreement with certain purchasers, pursuant to which we sold 3,000,000 shares of common stock at a price of $5.50 per share in a registered direct offering. The offering of the shares was made pursuant to our shelf registration statement on Form S-3 including the prospectus dated January 5, 2022 contained therein, and the prospectus supplement dated May 25, 2023.

In February 2024, we entered into a securities purchase agreement with certain purchasers, pursuant to which we sold 13,086,151 shares of common stock at a price of $4.585 per share in a registered direct offering. The offering of the shares was made pursuant to our shelf registration statement on Form S-3, including the prospectus dated January 5, 2022 contained therein, and the prospectus supplement dated February 28, 2024.

In a concurrent private placement, we issued unregistered warrants to purchase up to 13,086,151 shares of common stock at an exercise price of $4.906 per share (provided, however, that the purchaser may elect to exercise the warrants for pre-funded warrants in lieu of shares of common stock at an exercise price of $4.906, minus $0.001, the exercise price of each pre-funded warrant). These warrants are immediately exercisable for shares of common stock or pre-funded warrants in lieu thereof, and will expire on the earlier of (i) three and one-half years following the date of issuance and (ii) 30 days following our public disclosure of the acceptance of an NDA for cytisinicline by the FDA in a Day 74 Letter or equivalent correspondence. The shares of common stock issuable upon exercise of the warrants (or pre-funded warrants, as applicable) were subsequently registered pursuant to our registration statement on Form S-3, which was declared effective on May 6, 2024.

The registered direct offering raised total gross proceeds of approximately $60.0 million, and after deducting approximately $3.9 million in placement agent fees and offering expenses, we received net proceeds of approximately $56.1 million.

Stock Option Summary

We grant stock options that vest over time in accordance with terms as determined by our Board, which are typically four years for employee and consultant grants and one to three years for Board option grants. We also grant stock option awards that vest in conjunction with certain performance conditions to executive officers, employees and consultants. At each reporting date, we are required to evaluate whether achievement of the performance conditions is probable. Compensation expense is recorded over the appropriate service period based upon our assessment of accomplishing each performance condition. The expiration date for each option is set by our Board, which is typically seven to ten years. The exercise price of the options is determined by our Board.

The expected life was calculated based on the simplified method as permitted by the SEC’s Staff Accounting Bulletin 110, Share-Based Payment. We consider the use of the simplified method appropriate because of the lack of sufficient historical exercise data following the 2017 Merger Agreement between Achieve Life Sciences, Inc. and OncoGenex Pharmaceuticals. The computation of expected volatility was calculated based on the historical volatility of the shares of our common stock. The risk-free interest rate is based on a U.S. Treasury instrument whose term is consistent with the expected life of the stock options. In addition to the assumptions above, as required under ASC 718, management made an estimate of expected forfeitures and is recognizing compensation costs only for those equity awards expected to vest. Forfeiture rates are estimated using historical actual forfeiture rates.

These rates are adjusted on a quarterly basis and any change in compensation expense is recognized in the period of the change. We have never paid or declared cash dividends on our common stock and do not expect to pay cash dividends in the foreseeable future.

As of June 30, 2024, the total unrecognized compensation expense related to stock options granted was $3.5 million, which is expected to be recognized as expense over a period of approximately 1.62 years from June 30, 2024.

[d] Loss Per Share

For the six months ended June 30, 2024, a total of 21,219,368 shares, consisting of warrants to purchase 18,175,179 shares, options exercisable for 1,928,439 shares and 1,115,750 restricted stock units, have not been included in the loss per share computation, as their effect on diluted per share amounts would have been anti-dilutive. For the same period in 2023, a total of 7,090,100 shares underlying options, restricted stock units and warrants have not been included in the loss per share computation. Additionally, the outstanding Convertible Term Loan is included in the calculation of diluted per share amounts only if its inclusion is dilutive for periods during which the notes were outstanding. As of June 30, 2024, the outstanding Convertible Term Loan was not included in the calculation of diluted per share amounts as its effect would have been anti-dilutive.

[e] Restricted Stock Unit Awards

We grant restricted stock unit awards that generally vest and are expensed over a four-year period. We also grant restricted stock unit awards that vest in conjunction with certain performance conditions to certain executive officers, key employees and consultants. At each reporting date, we are required to evaluate whether achievement of the performance conditions is probable. Compensation expense is recorded over the appropriate service period based upon our assessment of accomplishing each performance condition. For the three and six months ended June 30, 2024, we recorded a compensation expense of $0.6 million and $1.1 million, respectively, related to these awards, compared to $0.5 million and $1.0 million for the three and six months ended June 30, 2023.

As of June 30, 2024, we had approximately $2.5 million in total unrecognized compensation expense related to our restricted stock unit awards that is to be recognized over a weighted-average period of approximately 1.25 years.

[f] Non-employee options and restricted stock units

We recognize non-employee stock-based compensation expense over the period of expected service by the non-employee. As the service is performed, we are required to update our valuation assumptions, re-measure unvested options and restricted stock units and record the stock-based compensation using the valuation as of the vesting date. This differs from the accounting for employee awards where the fair value is determined at the grant date and is not subsequently adjusted. This re-measurement may result in higher or lower stock-based compensation expense in the Consolidated Statements of Loss and Comprehensive Loss. As such, changes in the

market price of our stock could materially change the value of an option or restricted stock unit and the resulting stock-based compensation expense.

[g] Employee Share Purchase Plan

Our Board and stockholders approved the 2017 Employee Stock Purchase Plan, or ESPP, in August 2017. Contributions are made by eligible employees, subject to certain limits defined in the ESPP. The number of shares available for future purchases under the ESPP is 556,270 shares. All shares purchased under the ESPP are new share issuances. For the three and six months ended June 30, 2024, we recorded a compensation expense of $0.1 million and $0.1 million, respectively, related to the current ESPP offering period. For the three and six months ended June 30, 2023, no compensation expense was recognized related to our ESPP as we did not have an active offering period.

During the three months ended June 30, 2024 and 2023, no shares were purchased under the ESPP.
